Numerical Simulation of Air Jet Attachment to ConvexWalls and Application to UAV
(Lecture Notes in Computational Science and Engineering, 2015)
In this paper, we present a numerical study of the wall jet flow over a convex surface, viz. the Coanda wall jet, and its application to a conceptual Unmanned Aerial Vehicle (UAV) design which uses the Coanda effect as a ...
On the improved finite volume procedure for simulation of turbulent flows over real complex terrains
(Journal of Computational Physics, 2015)
This article presents a new and substantially improved finite volume procedure for simulation of incompressible flows on non-orthogonal grids. Cell-centered least-squares gradients are obtained in a robust and highly ...
Modeling air concentration of fly ash in Belgrade, emitted from thermal power plants TNTA and TNTB
(Process Safety and Environmental Protection, 2017)
The aim of the study was to estimate if dust/fly ash emitted into the atmosphere from chimneys and the ash disposal sites of the thermal power plants Nikola Tesla A and B in Obrenovac could increase the concentration of ...
On the use of small and cheaper sensors and devices for indicative citizen-based monitoring of respirable particulate matter
(Elsevier, 2015)
Respirable particulate matter present in outdoor and indoor environments is a health hazard. The particle concentrations can quickly change, with steep gradients on short temporal and spatial scales, and their chemical ...
Experimental and Numerical Investigation of the Primary Fragmentation of a Lignite during Fluidized-Bed (FB) Devolatilization
(Energy and Fuels, 2015)
The paper presents a comparison between experimental and model results of primary fragmentation of a lignite coal in a fluidized bed (FB). In the experiments, the char particle size distribution and the general indicators ...
The boiler concept for combustion of large soya straw bales
(Energy, 2009)
In one of the largest agricultural companies in Serbia, with over 2000 ha of soya plantations, there are 4000 t/year of baled soya straw produced. Soya straw biomass is planned to be used as a renewable energy source for ...
Numerical model of gaseous fuel jet injection into a fluidized furnace
(International Journal of Heat and Mass Transfer, 2009)
The paper presents a fluid-porous medium model, developed for stationary 2D predictions of fluidized bed. Dense phase is considered a fixed porous medium, while gas-particle interactions and bubbling phase are modeled ...
Sulfur release during combustion of Serbian coals
(Fresenius Environmental Bulletin, 2003)
The sulfur release during combustion of six Serbian coals of different rank (from lignite to semi-anthracite) and sulfur content (0.28 - 6.04 %) was determined by analyzing the content of various sulfur forms in coal, char ...
Denitrification techniques for biomass combustion
(Renewable and Sustainable Energy Reviews, 2018)
In order to achieve the main Applicable combustion control systems in grate-fired bogoals of sustainable development through the harmonization of rising energy needs with environmental protection, modern society promotes ...
Light controlled metallo-drug delivery system based on the TiO(2-)nanoparticles and Ru-complex
(Journal of Photochemistry and Photobiology. A: Chemistry, 2017)
We studied the colloidal TiO2 nanoparticles as a carrier for controlled delivery of the ruthenium complex to the melanoma cell line. The system demonstrated slower complex release upon visible and increased release rate ...
